Upon becoming Chief Mechanical Engineer of the LNER, Thompson sought to create an unstreamlined, mixed traffic version of Gresley#s A4 Pacific locomotives. Being unable to secure permission to construct new locomotives, Thompson decided to rebuild the 2-8-2 P2 Class locomotives as the new A2/2 Class. Thompson advocated divided drive, a system in which the middle cylinder drove the forward two of the six driving wheels whilst the outside cylinders drove the middle two.
